[Jukebox-list] AMI JBM200 Tropicana question

Hi all, My JBM200 Tropicana has gone from intermittently failing readout to now solid failure to readout and start the transfer circuit.  Read in circuity is fine.  The selected pin sets properly on the pin assembly.  When the magazine motor starts and moves the magazine and stopping switch gear, the stopping switch finds the selected pin but jumps right over it without stopping and starting the transfer cycle.  My manual shows that Control Relay R operates along with the shift solenoid through the stop switch when a pin is encountered.  My question is:  Where in the heck is control relay R?  I've found R1, R2, and R5 but cannot find R. in the machine or the manual.

Thanks, Dean
